APC Thin Electric Propellers or APC "E" props as they are often referred to, are a range of electric propellers produced in the USA by Landing Products. Landing Products have been producing propellers since around 1989 and their vast range of glow and electric propellers is widely accepted as offering excellent performance and value. In comparison with APC Slow Flyer propellers, APC Thin Electric propellers are generally designed for higher RPM applications and as such have a stronger hub area and a much more rigid blade structure. The Slow Flyer E-Props are also designed to provide much more responsiveness at low RPM. Thin electric, slow-fly, and multi-rotor propellers typically blend the low Reynolds number Eppler E63 airfoil (inboard) with a Clark-Y similar airfoil near the tip.
